spoon dc5 typr r

Hey new to the site and I am planning a swap in my 02 si k20a with a spoon dc5 block. I am going type r all the way obviously and I am wondering if the spoon block would be worth the coin of if i should just get a used jdm complete set up and tear it down to rebuild. The spoon block is 4600 direct from the factory but for a bit more i can get a tranny too if i go the used jdm. I am just afraid to get a used block mod it up and have castrophic failure.
